Am I using the len function right?

Can someone look at this and point me in the right path?

groups.py 
musical_groups = [
    ["Ad Rock", "MCA", "Mike D."],
    ["John Lennon", "Paul McCartney", "Ringo Starr", "George Harrison"],
    ["Salt", "Peppa", "Spinderella"],
    ["Rivers Cuomo", "Patrick Wilson", "Brian Bell", "Scott Shriner"],
    ["Chuck D.", "Flavor Flav", "Professor Griff", "Khari Winn", "DJ Lord"],
    ["Axl Rose", "Slash", "Duff McKagan", "Steven Adler"],
    ["Run", "DMC", "Jam Master Jay"],
]

for group_members in musical_groups:
    group_members = ", ".join(group_members)
    if len(group_members) == 3:
        print("Group {}: {}".format(musical_groups, group_members))

# your logic is correct, only thing, your answers are not approached towards, 
# exactly for what the question is asking for

for group_members in musical_groups:
    group_members = ", ".join(group_members) # this should go below the if condition, with not assigning to a variable instead printing
    if len(group_members) == 3: #this is correct
        print("Group {}: {}".format(musical_groups, group_members)) # this is complicating, not needed take this line oof
